THOMAS C. JOHNSON, OF NEVJ HAVEN, CONNECTICUT, ASSIGNOR TO WINCHESTER- REPEA'IING ARMS 00., OF NEW' HAVEN, CONNECTICUT, A CORPORATION.

COMBINED BOX-MAGAZINE AND FINGER-GUARD FOR BOLT-ACTION FIREARMS.

Application filed August 11, 1916.

To all whom it may concern:

Be it known that I, THOMAS C. JOHNSON, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Combined Box-Magazines and F inger-Guards for Bolt-Action Firearms; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings consti-. tute part of this application, and represent m-- Figure 1 a plan view of my improved Combined box-magazine and finger-guard for bolt-action firearms.

Fig. 2 a view thereof in side elevation, partially broken away.

My invention relates to an improved combined box-magazine and finger-guard for bolt-action firearms, the object being to produce an improved combined part adapted to be converted for cartridges of different sizes, on the ascending scale.

With these ends in view, my invention consists in a convertible combined boxmagazine and finger-guard for bolt-action firearms, having certain details of construction as will be hereinafter described and pointed out in the claim.

In carrying out my invention, I produce a box-magazine 2 and finger-guard 3 integral with each other and of any approved form as to details. The inner faces of the side walls of the box-magazine 2 are formed with integral, opposite, inwardly extending cartridge-positioning abutments 4 which are initially made long enough to extend sufliciently toward each other to position the smallest cartridges that would ever be used in bolt-action guns of the'type for which my improved part is designed. In case it is desired to use cartridges of the next Specification of Letters Patent.

Serial No. 114,379.

larger size, the ends of the abutments are correspondingly cut away and so on on the ascending scale to the largest sized cartridges that would ever be used in the guns.

It will be understood from the foregoing that initially the abutments t are adapted in length for the smallest sized cartridges and are cut away as required for cartridges of larger size up to the largest, whereby my improved part may be said to be convertible, though convertible only on the ascending scale, since the abutments 4 when once cut away, cannot afterward be elongated to adapt the part to handle smaller cartridges.

It will be noted that the inner face of the side walls of the box-magazine are cut away as at 5 between the abutments 4:, whereby the part is lightened. It will also be noted that the outer faces of the box-magazine are entirely smooth and that the cutting away of the abutments 4 does not affect the tegrity of the original structure, whereas sheet-metal box-magazines provided with rolled-in cartridge-positioning abutments are necessarily distorted by the rolling process, and moreover the outer faces of the side walls of the box-magazine are then broken by vertical grooves.

I claim A combined box-magazine and fingerguard for bolt-action firearms, the said magazine and guard being made in one piece, and the inner faces of the side walls of the magazine being formed with a plurality of inwardly projecting integral cartridge-positioning abutments for direct engagement by the cartridges, the said abutments of one face being located opposite the abutments of the other face and being initially made of full length for cartridges of the smallest size and adapted to be progressively cut away for cartridges of larger size on an ascending scale up to the largest.

THOMAS C. JOHNSON.
